One source (Origines familiae Bibranorum in Francia orientali utraque Silesia et Lusatia ...) reports that the family descends from a Sigmund von Bibra (Franconian Bibra family) who traveled to Silesia in the 11th century, however the different coat of arms casts doubt on the connection.
[1] The description with the published (c. 1860) print of Schloss Modlau describes the Bibran family as having split off from the Franconia Bibras five hundred years ago.
[2] The family appears for the first time with Sigmund von Bibra, who apparently followed Agnes von Babenberg, granddaughter of Emperor Henry IV and bride Duke Władysław II had come to Silesia from Franconia.
David Heinrich von Bibran-Modlau was the apparent last male member of the family in Silesia.
[4] The son-in-law Ernst Heinrich von Kölichen, who had incorporated the Bibran-Modlau name and coat of arms died (1832) with a daughter, Agnes, but no sons.
